Node v0.12.16 (Maintenance)

This is an important security release. All Node.js users should consult the security release summary at for details on patched vulnerabilities.

Notable changes:

• buffer: Zero-fill excess bytes in new Buffer objects created with Buffer.concat() while providing a totalLength parameter that exceeds the total length of the original Buffer objects being concatenated. (Сковорода Никита Андреевич)
• http:
  • CVE-2016-5325 - Properly validate for allowable characters in the reason argument in ServerResponse#writeHead(). Fixes a possible response splitting attack vector. This introduces a new case where throw may occur when configuring HTTP responses, users should already be adopting try/catch here. Originally reported independently by Evan Lucas and Romain Gaucher. (Evan Lucas)
  • Invalid status codes can no longer be sent. Limited to 3 digit numbers between 100 - 999. Lack of proper validation may also serve as a potential response splitting attack vector. Backported from v4.x. (Brian White)
• openssl:
  • Upgrade to 1.0.1u, fixes a number of defects impacting Node.js: CVE-2016-6304 ("OCSP Status Request extension unbounded memory growth", high severity), CVE-2016-2183, CVE-2016-6303, CVE-2016-2178 and CVE-2016-6306.
  • Remove support for loading dynamic third-party engine modules. An attacker may be able to hide malicious code to be inserted into Node.js at runtime by masquerading as one of the dynamic engine modules. Originally reported by Ahmed Zaki (Skype). (Ben Noordhuis, Rod Vagg)
• tls: CVE-2016-7099 - Fix invalid wildcard certificate validation check whereby a TLS server may be able to serve an invalid wildcard certificate for its hostname due to improper validation of *. in the wildcard string. Originally reported by Alexander Minozhenko and James Bunton (Atlassian). (Ben Noordhuis)
